When connecting loudspeaker systems to an amplifier, it is recommended
that the return resistance of the cable used is less than one tenth of the
nominal impedance of the system or systems in parallel. The table below
gives an indication of the maximum permissible cable runs for various
conductor cross-sectional areas.

The WT15, WT2 and WT3 may be used to cover the full-frequency range –
either distributed singly or arrayed in multiples. The WX3A and DX1
controllers provide appropriate system-specific low frequency equalisation
for full-frequency operation. Where additional low frequency output is
required, a WS2A sub-bass system driven from a separate amplifier fed
from the sub-bass output of a WX3A or DX1 controller can be added.
Wavefront Theatre Series loudspeakers combined with the appropriately
configured controller exhibit an essentially flat on-axis frequency response.
Equalisation to compensate for a particular acoustic environment may be
performed where required. Where loudspeakers are arrayed, they may
benefit from a degree of equalisation to reduce the effect of the low/mid
build up and tilting of the response inherent in the use of multiple arrayed
enclosures.
